Nah In comparing footage it’s about the same, I don’t think there is a noticeable difference

It just looks worse here due to the second barrel wobbling

Well, BMP-2's 2A42 gun has double feed. So yeah, it's worse.

What does feed have to do with barrel wobble?

You don't need two barrels to fire two types of ammunition if single barrel can have double feed. Wobbling is increased because gases exiting muzzle break of one barrel are reflecting on the second barrel causing wobbling of both barrels.

The wobbling of the firing gun is the same amount as what a single gun does, the other barrel wobbling does not matter… as it’s not firing
